GF 300 B and GF 300 T: Ball nose and Torus end mills
for high performance milling in materials < 62 HRC
The die and mold industry places ever higher demands
on milling cutters – primarily with regard to accuracy and
tool life. Therefore, Guhring’s cutting tool program now
includes radius milling cutters that are perfectly adapted
to satisfy these demands and provide optimal machining
results thanks to application orientated geometries,
carbide grades and coatings.The advantages are especially
high form and contour accuracy of the workpiece, minimal
wear and therefore excellent tool life.
Reduced neck ground The special features of Guhring’s ball nose milling cutters
for collision reduction are:
outside diameter and the radius is ground in one-pass
sradius point geometry with constant helix-radius-
correction
reduced neck ground for collision reduction with protruding
edges

Wear comparison:
Guhring’s seamless radius geometry reduces wear and provides a
considerably longer tool life in comparison with tools ground with
conventional full radius.
